现在人们普遍认识到，复杂工程系统生命周期中的许多重要事件是无法事先预见的。从它在生态系统中的起源，没有使用预见的操作，弹性理论规定假定对未来的无知，并设计系统来管理意外事件，无论它们可能采取什么形式。然而，关于什么构成弹性系统以及对工程系统的影响，仍然存在许多困惑。本文分析了弹性文献中的251个定义，旨在澄清弹性概念中的关键区别。问什么，什么，以及如何恢复，我们首先区分系统服务于高端和系统本身就是目的，并在这些，性能变量被最小化，保存，或最大化。其次，我们区分系统的不利事件，不利的变化，动荡，有利的事件，有利的变化，和变化。最后，我们区分系统能够恢复，吸收，改善，优雅的退化，最小的恶化，和生存。总之，这些区别概述了弹性系统的形态，并提出了主要设计问题的答案，这是任何弹性工程系统必须问的。
It is now widely recognized that many important events in the life cycle of complex engineering systems cannot be foreseen in advance. From its origin in ecological systems, operating without the use of foresight, resilience theory prescribes presuming ignorance about the future, and designing systems to manage unexpected events in whatever form they may take. However, much confusion remains as to what constitutes a resilient system and the implications for engineering systems. Taking steps toward a synthesis across a fragmented body of research, this paper analyses 251 definitions in the resilience literature, aiming to clarify key distinctions in the resilience concept. Asking resilience of what, to what, and how, we first distinguish systems serving higher ends and systems that are ends in themselves, and, within these, performance variables to be minimized, preserved, or maximized. Second, we distinguish systems subject to adverse events, adverse change, turbulence, favorable events, favorable change, and variation. Finally, we distinguish systems capable of recovery, absorption, improvement, graceful degradation, minimal deterioration, and survival. Together, these distinctions outline a morphology of resilient systems and suggest answers to the principal design questions, which must be asked of any resilient engineering system.
